Hi

Thanks for contacting us. I am afraid to say that there is no default option like this. But you can do it via custom CSS. As its customization support that's why we are not able to help you. You have to customize it yourself. This link may help you:

Hi Paul. Thanks it is what i was meaning :)

I tried add circle shape in corner of image content with pseoudo element but it moves if i change screen size so need something different.

You have to hire somebody to help you, it's customization task.
